Title: code 11 fix
Post by: jbshocks on February 28, 2017, 02:16:14 PM



A lurker on the site was having a persistent code 11 issue in a universal ultra.   You can see the failed capacitor on the power supply board in the attachment.  It is 4.7uf 50v 105 degree cap.   It sits very close to a coil so I suspect it overheated and we will start to see more failing.

Great job helping out! That guy was lucky you live so close to him!


For those who don't know, code 11 is low voltage seen by the mpu board. Usually a power supply issue, might also be the mpu itself or foreign object shorting out the board or backplane (screws and coins come to mind)
